Skew Compensation Adjustments (Emerge EMS1000MP-R Receivers Only)

The twisted pair cabling used to link the Emerge EMS units

consists of four pairs of wires per cable. Three of these pairs are used to convey the red, green and blue video signals. Due to slight differences in twist rate between the wire

pairs, the red, green and blue video signals may not arrive at precisely the same time. This effect is visible as separate color shadows on high contrast images and is particularly apparent when using higher screen resolutions over long distances and also when using certain types of category 5e cables.

Skew compensation adjustments are made using two rotary dials, the first affects the relationship between the green and blue color signals (SKEW GB) while the second (SKEW RG) operates similarly on the red and green signals. Each dial

delays one of its stated colors in relation to the other. By using both dials it is possible to correctly align all three colors. The effects of skew are easiest to view and adjust when distinct red, green and blue elements, in close proximity, are present within the screen image. An appropriate test pattern is supplied on the Emerge EMS CD-ROM (To Display the Supplied Skew Test Pattern) or alternatively you can create your own test pattern as discussed below.

NOTE: Both video outputs are equally affected by your skew adjustments.

To Create a Skew Test Pattern

1.Run any image creation/editing application, such as the Paint program supplied with Windows.

2.Using the image application create three stacked horizontal rectangles (one red, one green and one blue) that fill the width of the screen.

3.Draw a vertical black line down across the colored bars and then repeat this vertical line at intervals along the width of the colored bars. These lines create breaks across the colors and give you more opportunities to view the horizontal position of each color relative to the others.
